EXTRACTOR MECHANISM FOR BREECH-LOAD'ING GUNS.

SPECIFICATION forming part of Letters Patent No. 378,169, dated February 21, 1888.

(No model.)

To aZZ whom it may concern:

Be it knownthat I, WILHELM LORENZ, of Carlsruhe, in the Grand Duchy of Baden, Germany, have invented a certain new and useful Improvement in Extractors for Metal Cartridge-Gases in Breech-Loading Guns, of which the following is a specification.

The accompanying drawings form a part of this specification and represent means for carrying out the invention with modifications.

Figures 1, 2, and 3 are central horizontal sections through the rear portion of a gun constructed according to my invention. Fig. 1 shows the breech-block being inserted. Fig. 2 shows the parts in position for firing, and

Fig. 3 shows the ejector in act of throwing out a shell by the quick movement of the ejectorflap. The remaining figures show modifications. Fig. 4 is a horizontal section showing the parts in the position for firing. Fig. 5 is a corresponding section showing the parts in the position for ejecting the shell. Fig. 6 is a rear view of the breech block, sometimes termed the breech-wedge, detached. Fig. 6 is a cross-section through a portion of the breech-block in the plane of the firing-pin. Fig. 7 is a cross-section through the gunin the plane of the front of the breech-block. Fig. 8 shows two views of the ejector-flap detached. Fig. 9 shows two views of one of the latches detached. These last seven figures belong together and represent similar parts. The succeeding figures show further modifications. Fig. 10 is a central horizontal section showing sliding bolts in place of the latches before shown to operate the ejector-flap. Fig. 10 shows two views of the said bolts detached. Fig. 11 is a partial horizontal section showing a modification of the hinge of the ejectorfiap, and Fig. 12 is a partial horizontal section.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

The arrows indicating motions maybe differently marked in the several figures.

In all the figures the eXtractorA is a flat lever or flap having a semicircular recess which engages the cartridge-case O by matching under its base-rim c. The flap isprovided on one face with a rounded lip, a, extending in a straight line across the outer end, which lip engages in a corresponding groove in the gun D,with liberty to turn thereon. The other face of the flap at that end is formed-with stout projections or noses a a This flap A is so embedded in a corresponding recess in the front side of the breech-hole that the noses a? a project into the hole.

Referring to Figs. 1, 2, 3, and 4, latches d d are mounted in the breech-wedge B, one at each side, pressed forward by springs d. At the withdrawing of the breech wedge B by moving it in the direction of arrow I the latches d d strike against noses a a and thereby turn the extractor-flap A with a short quick turning motion around its collar aas a center. Thereby the cartridge-case C will be thrown backward with a short jerk and ejected. The latch es (1 d are arranged in such position relatively to cartridgehole B that the latter is at that time in line with the bore of the gun,

so as to permit the cartridge shell to pass through. The springs d cl force outward the latches d d,- but they will by yielding permit the easy passage of the breech-wedge inward when it has, as is sometimes required, been drawn wholly out of the gun.

B are shoulders in the breech wedge extending parallel to the rearface thereof. They act against corresponding smooth surfaces in the gun D, and serve as guides for the breechwedge in its opening and closing motion, compelling it to traverse in a line parallel to the rear face of .the breech-wedge. This insures a clear space for the ejector to move invwhen the breech-wedge is withdrawn.

The lip a of the extractor-flap is preferably embedded,as shownin Fig.1].,in arabbet at the surface, and secured thereto by the supporting-plate f and screws f,- or the extractor may be additionally connected by hinges, as shown in Figs. 1, 2, and 3, and in Fig. 12, which will form apivot for the same. latter cases,-in order that the breech-wedge may, if required, be conveniently drawn out, the extractor is made removable in the direction of arrow I by the unscrewing and removal of the plate f. In this form of the inventionthe grooves on the breech-wedge need not 6X tend through, and the rigid shoulders g g on the breech-wedge may push against the noses at a for ejecting the cartridge-cases.

In order to allow the pushing backward and forward of breech-wedgeB, the same is pro- In these i vided with grooves of corresponding form and depth.

Further modifications may'be made in the shapes and positions of latches d d, bolts 6 e, springs d d or e 6 and noses a a or their equivalents, without departing from the principle or sacrificing the advantages of the invention.

I claim as my invention- In a breech-loading gun, the gun D, having a rabbet at the outer edge of the breech-block opening, the ejector A, adapted to engage at its front edge under the rim 0 of the cartridge-shell C, said ejector having a lip embedded in said recess, whereon the ejector turns pivotally, and also having upwardlyextending noses a the plate f, and screws f, removably securing said plate to the gun over said rabbet, for the purpose set forth, in combination with the breech block B, having shoulders adapted to strike said noses when it is withdrawn, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.

WILHELM LORENZ.
